Spill closes Miss. River, shuts off exports

BELLE CHASSE, Louisiana (Reuters) - The largest petroleum spill to hit the Mississippi River since 2005's Hurricane Katrina snarled ship traffic on Thursday from New Orleans to the Gulf of Mexico and brought flows of grain and other key exports to a standstill.

The day after a ship collision shut down a 97 mile stretch of water, the river was a traffic jam of about 100 ships waiting to move along the vital link to Midwest grain elevators, coal terminals and other industrial facilities, Coast Guard officials said.

"Think in terms of days for the opening and think in terms of weeks for the cleanup," said Captain Lincoln Stroh of the U.S. Coast Guard. "Think in terms of weeks for the cleanup."

The river is a vital link carrying grain from production areas in the Midwest to export markets abroad. Between 55 and 65 percent of all U.S. corn, soybean and wheat exports leave from the Gulf of Mexico.

Officials deployed an armada of ships to contain the spill, a floating scrim of 420,000 gallons (1,590,000 liters) of No. 6 fuel oil that threatened to contaminate the area's drinking water.

"We still have a huge amount of oil moving down the river," Stroh told reporters at a news conference.

Cleanup crews are working to clear spilled oil from the center of the river and open a shipping lane there, he said.

The spill happened early Wednesday when the tanker Tintomara, owned by Whitefin Shipping Co of Gibraltar, hit an American Commercial Lines barge being pushed by the tug Mel Oliver.
